Incorrect phasing in power networks can have devastating and even deadly consequences. Yet phasing has, until now, been surprisingly hard to verify. This has changed with the introduction of an innovative phase verification system that makes use of the...

Harmonics in power systems are a major concern as they are becoming increasingly prevalent and they can give rise to serious problems that include excessive heating and premature equipment failure. While there is good general awareness of these issues, many...

Power transformers are costly and, in many cases, critical assets. This means that accurate information about their current condition is exceptionally useful, as it allows maintenance to be rationally planned and also allows incipient faults to be...

One of the best ways of enhancing the evaluation of results produced using time domain reflectometers (TDRs) is to make comparative measurements, as comparisons invariably show the details of faults much more easily and clearly.
